PROVIDENCE, R.I. (AP) — Gubernatorial hopeful and Providence Mayor Angel Taveras is set to unveil his policy plans on the environment.

The Democrat is scheduled to release details of his proposal Tuesday after helping members of Groundwork Providence's social-venture landscaping service plant trees in front of a residence and business in the city.

State Rep. Art Handy, the Democratic chairman of the House environment committee, is expected to join the mayor.

Taveras is running against Treasurer Gina Raimondo, political newcomer Clay Pell and 2010 independent candidate Todd Giroux in the September primary.

The four plan to attend a climate change forum Thursday at Brown University that's co-sponsored by the Environment Council of Rhode Island. Republican candidates Allan Fung and Ken Block are not participating.
